The surgical treatment of infantile flat foot. A new expanding endo-orthotic implant.

In the correction of flat foot in children, the fundamental requirement is to restore the normal relationship between the talus and calcaneus. To achieve this, the authors have devised an expanding orthotic implant which is inserted into the sinus tarsi. They discuss the indications and describe the surgical technique and the special instruments devised for fitting the device. The case material and first results after not less than 18 months follow-up are reported.
